Questions
How big is the SmartButtonPCB PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SmartButtonPCB use?
75 parts, built around the WS2812B-B/T, AO3400 and B3F-4055. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SmartButtonPCB KiCad files?
From the Pegoku/SmartButton repository on GitHub, at the commit this page was made from: the board is SmartButtonPCB/SmartButtonPCB.kicad_pcb and its schematic SmartButton/SmartButton.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmartButtonPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pegoku before reusing the design.
